305-020-555-268

Edgeboard Connectors Overview

The EDAC Inc. 305-020-555-268 is a standard card edge connector from the 305 series, designed for dual female connections on non-specified double-sided cards. It features a 3.96 mm (0.156 inch) pitch with 20 positions arranged in two rows. The unit utilizes gold-plated copper alloy contacts and a green thermoplastic polyester housing. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 20 contact positions for robust signal transmission
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic polyester housing provides structural integrity and thermal stability
• Vertical panel mounting style facilitates secure installation in chassis applications

Edgeboard Connectors Applications

• Industrial control systems requiring durable card edge interfaces
• Telecommunications equipment utilizing standardized board connections
• Test and measurement instrumentation needing reliable signal pathways
• Automotive electronics modules demanding stable electrical connections

Edgeboard Connectors Procurement Notes

Verify that the specific suffix '268' corresponds to the required panel mount orientation and housing color. Confirm compatibility with the target PCB thickness, typically ranging between 1.37 mm and 1.78 mm. Ensure the application environment remains within the specified operating temperature limits. Check for RoHS compliance requirements if applicable to your manufacturing standards. Validate pin count and row configuration against the design schematic before ordering.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel mount solution is required for double-sided cards. The 3.96 mm pitch suits applications needing wider spacing between contacts. Consider the 5 A rating for power distribution or high-current signal lines. The gold plating is suitable for environments where oxidation resistance is critical. Evaluate the thermoplastic housing material for adequate thermal performance in enclosed spaces.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting styles and position counts. The series is known for its versatility in connecting edgeboards to backplanes or chassis panels. Similar parts in the series differ by pitch, row count, and mounting orientation. The 305 series provides a standardized interface for modular electronic designs across multiple industries.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with matching 20-position dual-row configurations. Verify that alternative parts maintain the same 3.96 mm pitch and panel mount orientation. Cross-reference specifications for current rating and temperature range to ensure functional equivalence. Consult manufacturer catalogs for updated part numbers with identical mechanical dimensions.
